Abstract
A power transfer device adapted for use in combination with a power transmission. The transfer device includes a housing, an input shaft rotatably mounted within the housing for drive connection to an output shaft of the transmission, an output shaft rotatably mounted within the housing for rotation relative to the input shaft, a planetary gear unit arranged within the housing and having an input element mounted on the input shaft for rotation therewith and an output element connectable to the output shaft, and a sleeve member axially slidably mounted on the output shaft and shiftable between a first position in which it effects a drive connection between the input and output shafts and a second position in which it effects a drive connection between the output element of the gear unit and the output shaft. A bearing retainer is secured to the housing to retain a bearing carried on the housing for supporting thereon the input shaft, and an oil pump assembly is contained within a cavity of the bearing retainer and mounted on the input shaft at the outside of the housing to be driven by rotation of the input shaft. The pump assembly is arranged to pump up lubricating oil stored in the housing and supply it into an axial bore in the input shaft.
